Phyllanthus tenellus Roxb., a native of Mascarene Islands, though originally described from a population raised in the Indian Botanic Garden, is reported as an adventive from Salem district in Tamilnadu and from Greater Bombay in Maharashtra. It is also being lectotypified with Roxburgh's unpublished Flora Indica drawings.Full Text

The study reveals that 'Phyllanthus nirui in Fora of British India is a mixture of three distinct species, viz., P. amarus Schum. & Thonn., P. fraternus Webster and P. debilis Klein ex Willd., the true P. niruri Linn, being endemic to West Indies. It is further observed that true P. debilis Klein ex Willd. (1804) is not correctly recognised in any Indian Flora and the plant that goes under the name is an altogether different species-P. debilis Herb. Ham. ex Hook.f. (1887), which however, being a later homonym is to be replaced by P. aity-shawii Brunei & Roux (1984). P. mukerjeeanus Mitra & Bennet has been found to represent juvenile form of P. debilis Klein ex Willd., hence reduced to the synonymy of that species. To facilitate proper identification a key to the different taxa of this complex in India is provided and their diagnostic characters are described and illustrated.Full Text

The study reveals that the concept of Phyllanthus parvifolius in Flora of British India is a mixture of altogether two different species save P. parvvolius. These are eastern Himalayan species P. pseudoparvifolius described here anew. and semiarid north-west Himalayan elements of P. clarkei. In addition to identifying these two species as representing P. parvifolius, a part of the semiarid elements of P. clarkei was also identified as P. praetervisus and hence P. praetervisus was reduced to the synonymy of alleged P. parvifolius. True P. praetervisus however, remained incognito in all the floras of the region as a constituent of P. clarkei described originally as a complex species from eastern Himalaya, while P. parvifolius, a species endemic to (? central) Nepal, also remained mixed up with the two aforesaid constituents of alleged P. parvfolius even in Nepal Flora.Full Text

The paper is a brief historical resume on the genesis and development of familial concept as a natural unit in plants and its nomenclature. It explains in the backdrop of Latin grammar, how names with diverse terminations once dominated family nomenclature in taxonomic literature. It also narrates the logical efforts that followed to rationalize the family names to its present state leaving room for use of alternative names for a few angiosperm families. Besides, the paper discusses the proper use of the names Leguminosae, Fabaceae and Papilionaceae, and the associated problems.Keywords

Studies on several populations of Nymphaea rubra in the Howrah, Hooghly and 24-Parganas districts in West Bengal and Barisal district in Bangladesh reveal that this species, claimed to be a native of Bengal, never sets fruit in nature. The plant propagates though stolons and vegetative buds and, in exceptional cases, by proliferation of flowers. The report of meiotic irregularity and high incidence of polysomaty and pollen sterility is indicative of its apomictic nature. The nomenclature of the plant has been discussed.Full Text
